MATTRESS-FRAME AND BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 448,209, dated March 17, 18919 Application filed October 24, 1888. Serial No, 288,999- (No model.) Patented in England November 10, 1885, No. 13,640;

To all whom it may concern.-

Be it known that we, ISAAC CHORLTON and GEORGE LAMB Soorr, subjects of the Queen of Great Britain and Ireland, residing at Manchester, county of Lancaster, England, have invented certain Improvementsin the Construction of lllattress-ljrames and Bedsteads, (for which we obtained apatentin Great Britain, No. 13,640, dated November 10, 1885,) of which the following is a specification.

Our said invention has reference to the con struction of bedsteads and mattress-frames, and is more particularly applicable to the production of the lighter classes of bedsteads and n1attress'framessuch, for example, as are used for camp, barrack, and ambulance purposes, or for ships berths-and which can be folded together and packed into small space; and in order that our said invention may be properly understood we will now proceed more particularly to describe the same, reference being had to the annexed two sheets of d rawiu gs, and to the letters marked thereon.

Figure 1, Sheet 1,is a side elevation of a camp or barrack bed constructed in accordance with our invention. Fig. 2 is a plan of the same. Fig. 3 is a side elevation of asimilar bed intended to fold together. Fig. 4: is a View similar to Fig. 3, showing the legs and rests folded together. Fig. 5is aplan of Fig. 4-. Fig. 6, Sheet 2, is a side elevation of a camp-bed intended to fold into half its length. Fig. 7 shows such a bed folded. Figs. 8, 9, 10, 11, 12, 13,-1i, and 15 are detail views of parts of the bed.

Referring to Fig. 1, the frame is composed of the side members a, which are made of ordinary metal tubing, the two sides a being connected at each end by angle-iron bars I), so as to form a parallelogrammic frame.

The means for uniting the angle-bars Z) to the ends of the tubes a is more clearly shown in an enlarged view in Figs. 10 and 11, Sheet 2, of the drawings. In Fig. 10 the tube CL and an gle-iron b are shown in section. That part of the angle-iron which comes opposite to the end of the tube Cb is pierced by a hole of the same diameter as the interior of the tube, and a stud c is introduced through the hole, so as to enter the tube for a short distance. A rivet or pin d, or it mightbe abolt or screw, is driven through both tube and stud, so as to hold them together, the angle-iron I) being thus firmly held between the end of the tube and the head of the stud c. This method of attachment is employed at each corner of the frame shown at Figs. 1 and 2, and we thus obtain a light and secure rectangular frame or bedstead.

In Figs. 1 and 2 the frame is supported by fixed legs, which consist, as shown, of T-couplings e, secured to the side tubes or. Short lengths of tube fconnect the couplings c with feet g. The frame may be supported in an inclined position, as shown, or it may be in a horizontal plane, if desired. The mattresssurface, which is applied to the hereinbeforedescribed frame, may consist of any known or suitable material, but is preferably of metallic woven or linked wire or chain or laths stretched between the two ends and secured thereto by known or suitable means. In the example, as shown at Fig. 2, we apply thin metallic laths h, which are hooked or connected to the end angle-bars by interposed springs 2', which give the necessary elasticity to the mattress-surface formed by the laths. To preserve the relation of the la'ths to each other and to the frame, we employ links or hooks 7c, which connect the laths to each other and to the side tubes. Fixed hinged or removable head and feet restsl may be applied to theframe-for instance, bythe meansshown in the detail perspective view, Fig. 145, in which the angle-bar has formed with or attached to it perforated lugs I), through which and through corresponding lugs l on the rest Z are passed removable pivot-pins Z The frame shown in Figs. 1 and 2 is not intended to fold together; but we will now proceed to describe a frame which may be folded together so as to occupy little space when being transported from place to place. Figs. 3, 4, and 5 show such a frame, Fig. 3 being a side elevation of the frame when opened out for use, while Figs. 4 and 5 are views of the frame folded together for storage or trans port. As will be seen, the tubular sides aand angle-iron ends I) are secured together in the manner already described; but the legs or supports m arecapable of being turned on the side tubes, so as to lie close to the mattresssurface. Ne form a slot or groove in each of the couplings e, Which receives a fixed pin 0,

projecting from the tube a. In Fig. 3 this pin 0 has entered the slot and prevents -the coupling from turning on the tube a, thus keeping the legs in a vertical position. Pinching-screws a: are employed, as shown, to still further secure the couplings in position. If it is desired to fold the legs into the same plane as the mattress-surface, the pinchingscrews 00 are loosened and the couplings are slid upon the tubes at until the slot in each has cleared the pins 0, when the leg may be turned into the position shown at Fig. 5. A pin p may be provided to prevent the legcoupling from sliding farther than is necessary. I

As a substitute for the pins 0 to hold the legs in position we may securea separate stop 0 to the tube, as shown at Fig. 8, Sheet 2, of the drawings, which stop 0 has two, three, or more projecting fingers which enter corresponding recesses in the coupling 6 and prevent the same from turning on the tube when thrust into gear with the stop 0. 7

By another modification the stop 0 might be formed, as at Fig. 9, having a projection 0', which enters a recess 6 in the coupling 6, so as to prevent turning when the two parts are brought into interlocking contact, as shown at Fig. 9. The head and foot rests Z are also hinged, so as to be capable of being turned into the position shown at Figs. 4 and 5. In the example the legs are of equal length, so that the frame lies parallel with the ground-line; but its position might be inclined, as in Fig.1.

Figs. 6 and 7, Sheet 2, are views of a bed similar to those already described, but jointed in the middle, so as to fold into half its length. The tubes a may be hinged together or connected by a stud or core 7, Figs. 7 and 15, the

joint being strengthened or secured by a sleeve 8, which can he slid back when it is desired to fold the two halves of the frame together, as shown at Fig. 7. The legs and head and feet rests are folded, as already described.

In Figs. 12 and 13 the well-known dovetail for connecting the sides or frame to the uprights is formed on the outer end of the connecting-stud c, the dovetail and flange w taking the place of the stud-head shown in Figs. and 11. A flange 6 may be formed on the dovetail, so as to mask the end of the angleiron I) and give it a solidity of appearance from the side.

What we claim is I 1. In a camp-bed having sides aof metal tubing and ends I) of angle-iron, the device for connecting the ends to the sides, consisting of the plug 0, passing through the angleiron end I) and into the end of the tubular side a, in combination with the transverse rivet or bolt d, engaging said side and plug, substantially as described and shown.

2. In combination with a folding camp-bed having sides a, of metal tubing and ends I) of angle-iron, and the legs m, in combination with the slotted T-piece e, secured to said legs, receiving the sides a, and provided with the set-screw 0c and the stops 0 and p on said sides, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
